how to purchase new rubber gaskets for fuel caps

[Gfeldman]

Does anyone know where to get  new rubber gaskets for fuel caps- mine are starting to show cracks after 2 years.

I am going to order some from the O Ring Store, George.  I will let you know when I have them.

O-rings of the proper material should last a lot longer than 2 years, especially since they are not in contact with the fuel. Do we know why they failed so soon, and was it both caps, or perhaps just the left wing cap?

Hi Eric,

I really don't know why. The gaskets are not in direct contact with fuel but they are constantly exposed to the fumes. What do yours look like?

I'll look next time I'm at the hangar - maybe Sunday. I haven't noticed any problems.

I examined the o-rings on my fuel caps today. They appear to be in excellent condition, with only some silver discoloration from the aluminum seat. The o-rings are at least 4 years old, as I've had the plane for since March 2014, and never replaced them.

Most my fuel has been ethanol-free auto gasoline, with 100LL being the only other fuel. I don't know if the type of fuel makes any difference, however.
